This is a known issue with Windows XP and the current GoPro CineForm Studio. There is a workaround, however... Here's what you can do to get it to work:
1. take a series of time lapse photos on your GoPro Hero2
2. connect the camera to your PC and copy them into a folder
3. disconnect the camera from the PC
4. right-click on the first image and select [Properties]
5. Under the Summary tag, notice the Title field is blank
6. enter the Title name to match the image and apply the change by clicking ok or apply
7. open CineForm Application (camrea not attached)
8. select [Import New Files], navigate to the folder where your sequence is saved and select the first image of the series
9. drag the image into the New Files pane on the left
10. highlight the first clip in the [Import New Files] pane and selected [Import New Files] again.
11. highlight all the remaining images in the series and click [OPEN]. All the remaining images in the series should then import
12. When the image imports it should reflect the number of frames of all pictures in the directory to the end of the sequence without needing to import additional files
13. use the "Add Clip to Conversion List" button to add the newly created clip on the left side of the screen to the Conversion List column on the right side of the screen.
14. then click Convert All at the bottom of the right column to create a playable file. It may take a bit of time for a large number of files, but a status bar will track the percentage of processing until it is Complete.
